No. 09/586,221 filed Jun. 2, 2000, which is based upon U.S.Provisional Patent Application No. 60/138,408 filed Jun. 8, 1999, whichare incorporated herein by reference in their entireties.

BACKGROUND OF THE INVENTION

Light bars or emergency lights of the type used on emergency vehiclessuch as fire trucks, police cars, and ambulances, utilize warning signallights to produce a variety of light signals. These light signalsinvolve the use of various colors and patterns. Generally, these warningsignal lights consist of incandescent and halogen light sources havingreflective back support members and colored filters.

Many problems exist with the known methods for producing warning lightsignals. One particular problem with known light sources is theirreliance on mechanical components to revolve or oscillate the lamps toproduce the desired light signal. Additionally, these componentsincrease the size of the light bar or emergency lights which mayadversely affect the vehicles aerodynamic characteristics. Moreover,there is an increased likelihood that a breakdown of the light bar orlight source will occur requiring the repair or replacement of thedefective component. Finally, the known light bars and sources require arelatively large amount of electrical current during operation. Thedemands upon the electrical power system for a vehicle may thereforeexceed available electrical resources reducing optimization ofperformance.

The most common light sources being used in light bars or emergencylights include halogen lamps or gaseous discharge xenon lamps. Theselamps emanate large amounts of heat which is difficult to dissipate froma sealed light enclosure or emergency light and which may damage theelectronic circuitry contained therein. In addition, these lamps consumelarge amounts of current requiring a large power supply or large batteryor electrical source which may be especially problematic for use with avehicle. These lamps also generate substantial electromagnetic emissionswhich may interfere with radio communications for a vehicle. Finally,these lamps, which are not rugged, have relatively short life cyclesnecessitating frequent replacement.

Another problem with the known warning signal lights is the use offilters to produce a desired color. Filtering techniques produce moreheat that must be dissipated. Moreover, changing the color of a lightsource requires the physical removal of the filter from the light sourceor emergency light and the insertion of a new filter. Furthermore,filters fade or flake over time rendering the filters unable toconsistently produce a desired color for observation in an emergencysituation.

These problems associated with traditional signaling lamps areexacerbated by the fact that creating multiple light signals requiresmultiple signaling lamps. Further, there is little flexibility inmodifying the light signal created by a lamp. For example, changing astationary lamp into one that rotates or oscillates would require asubstantial modification to the light bar which may not be physically oreconomically possible.

The present invention generally relates to electrical lamps and to highbrightness light-emitting diode or “LED” technology which operates toreplace gaseous discharge or incandescent lamps as used as automotivewarning signal light sources.

Illumination lamps for automobile turn signals, brake lights, back-uplights, and/or marker lights/headlights frequently have accompanyingutility parabolic lens/reflector enclosures which have been used forutility warning signals or emergency vehicle traffic signaling.

These signaling devices as known are commonly referred to as “unmarkedcorner tubes,” or “dome tubes.” These signaling devices as knownfrequently utilize xenon gaseous discharge tubes or incandescent lampsas the illumination sources.

A problem with the prior art is the cost and failure rate of the known“unmarked corner tubes,” or “dome lights.” The failure rate of thesedevices frequently results in a significant amount of “down time” for avehicle to effectuate replacement. Further, an officer is frequentlyunaware that a vehicle light is inoperative requiring replacement. Thiscondition reduces the safety to an officer during the performance of hisor her duties. In addition, the reduced life cycle and failure rate ofthe known illumination devices significantly increases operational costsassociated with material replacement and labor. A need, therefore,exists to enhance the durability, and to reduce the failure rate, ofillumination devices while simultaneously reducing the cost of areplacement illumination source.

In the past, the xenon gaseous discharge lamps have utilized a sealedcompartment, usually a gas tube, which may have been filled with aparticular gas known to have good illuminating characteristics. One suchgas used for this purpose was xenon gas, which provides illuminationwhen it becomes ionized by the appropriate voltage application. Xenongas discharge lamps are used in the automotive industry to provide highintensity lighting and are used on emergency vehicles to provide avisible emergency signal light.

A xenon gas discharge lamp usually comprises a gas-filled tube which hasan anode element at one end and a cathode element at the other end, withboth ends of the tube sealed. The anode and cathode elements each havean electrical conductor attached, which passes through the sealed gasend of the lamp exterior. An ionizing trigger wire is typically wound ina helical manner about the exterior of the glass tube, and this wire isconnected to a high voltage power source typically on the order of 10-12kilowatts (kw). The anode and cathode connections are connected to alower level voltage source which is sufficient to maintain illuminationof the lamp once the interior gas has been ionized by the high voltagesource. The gas remains ignited until the anode/cathode voltage isremoved; and once the gas ionization is stopped, the lamp may be ignitedagain by reapplying the anode/cathode voltage and reapplying the highvoltage to the trigger wire via a voltage pulse.

Xenon gas lamps are frequently made from glass tubes which are formedinto semicircular loops to increase the relative light intensity fromthe lamp while maintaining a relatively small form factor. These lampsgenerate extremely high heat intensity, and therefore, requirepositioning of the lamps so as to not cause heat buildup in nearbycomponents. The glass tube of a xenon lamp is usually mounted on alight-based pedestal which is sized to fit into an opening in the lightfixture and to hold the heat generating tube surface in a light fixturecompartment which is separated from other interior compartment surfacesor components. In a vehicle application, the light and base pedestal aretypically sized to fit through an opening in the light fixture which isabout 1 inch in diameter. The light fixture component may have a glassor plastic cover made from colored material so as to produce a coloredlighting effect when the lamp is ignited. Xenon gas discharge lampsnaturally produce white light, which may be modified to produce acolored light, of lesser intensity, by placing the xenon lamp in afixture having a colored lens. The glass tube of the xenon lamp may alsobe painted or otherwise colored to produce a similar result, althoughthe light illumination from the tube tends to dominate the coloring; andthe light may actually have a colored tint appearance rather than asolid colored light. The color blue is particularly hard to produce inthis manner.

Because a preferred use of xenon lamps is in connection with emergencyvehicles, it is particularly important that the lamp be capable ofproducing intense coloring associated with emergency vehicles, i.e.,red, blue, amber, green, and clear.

When xenon lamps are mounted in vehicles, some care must be taken toreduce the corroding effects of water and various chemicals, includingroad salt, which might contaminate the light fixture. Corrosive effectsmay destroy the trigger wire and the wire contacts leading to the anodeand cathode. Corrosion is enhanced because of the high heat generatingcharacteristics of the lamp which may heat the air inside the lampfixture when the lamp is in use, and this heated air may condense whenthe lamp is off resulting in moisture buildup inside the fixture. Thebuildup of moisture may result in the shorting out of the electricalwires and degrade the performance of the emission wire, sometimespreventing proper ionization of the gas within the xenon gas dischargelamp.

Warning lights, due to the type of light source utilized, may berelatively large in size which in turn may have an adverse affect uponadjacent operational components. In addition, there is an increasedlikelihood for a breakdown of the light source requiring repair orreplacement of components.

Another problem with the known warning signal lights is the use ofrotational and/or oscillating mechanisms which are utilized to impart arotational or oscillating movement to a light source for observationduring emergency situations. These mechanical devices are frequentlycumbersome and difficult to incorporate and couple onto variouslocations about a vehicle due to the size of the device. Thesemechanical devices also frequently require a relatively large powersupply to engage and operate the device to impart rotational and/oroscillating movement for a light source. Power consumption of electricalcomponents for an emergency vehicle is of primary consideration forvehicle operators.

Another problem with the known warning signal lights is the absence offlexibility for the provision of variable intensity for the lightsources to increase the number of available distinct and independentvisual light effects. In certain situations it may be desirable toprovide a variable intensity for a light signal or a modulated intensityfor a light signal to provide a unique light effect to facilitateobservation by an individual. In addition, the provision of a variableor modulated intensity for a light signal may further enhance theability to provide a unique desired light effect for observation by anindividual.

No warning lights are known which are flexible and which utilize avariable light intensity to modify a standard lighting effect. Thewarning lights as known are generally limited to a flashing lightsignal. Alternatively, other warning signal lights may provide asequential illumination of light sources. No warning or utility lightsignals are known which simultaneously provide for modulated and/orvariable power intensity for a known type of light signal to create aunique and desirable type of lighting effect.

No warning signal lights are known which provide an irregular or randomlight intensity to a warning signal light to provide a desired lightingeffect. Also, no warning light signals are known which provide a regularpattern of variable or modulated light intensity for a warning signallight to provide a desired type of lighting effect. Further, no warninglight signals are known which combine a desired type of light effectwith either irregular variable light intensity or regular modulatedlight intensity to provide a unique and desired combination lightingeffect.

It has also not been known to provide alternative colored LED lightsources which may be electrically controlled for the provision of anydesired pattern of light signal such as flashing, pulsating,oscillating, modulating, rotational, alternating, strobe, and/orcombination light effects. In this regard, a need exists to provide aspatially and electrically efficient LED light source for use on anemergency or utility vehicle which provides the appearance of rotationor other types of light signals without the necessity of a mechanicaldevices. In addition, a need exists to provide a spatially andelectrically efficient LED light source for use on an emergency vehiclewhich provides a flashing, modulated, oscillating, rotational,alternating, and/or strobe light effects without the necessity ofmechanical devices.

In view of the above, there is a need for a warning signal light that:

(1) Is capable of producing multiple light signals;

(2) Produces the appearance of a revolving or oscillating light signalwithout relying upon mechanical components;

(3) Generates little heat;

(4) Uses substantially less electrical current;

(5) Produces significantly reduced amounts of electromagnetic emissions;

(6) Is rugged and has a long life cycle;

(7) Produces a truer light output color without the use of filters;

(8) Is positionable at a variety of locations about an emergencyvehicle; and

(9) Provides variable power intensity to the light source withoutadversely affecting the vehicle operator's ability to observe objectswhile seated within the interior of the vehicle.

Other problems associated with the known warning signal lights relate tothe restricted positioning on a vehicle due to the size and shape of thelight source. In the past, light sources due to the relatively largesize of light bars or light sources, were required to be placed on theroof of a vehicle or at a location which did not interfere with, orobstruct, an operator's ability to visualize objects while seated in theinterior of the vehicle. Light bars or light sources generally extendedperpendicular to the longitudinal axis of a vehicle and were thereforemore difficult to observe from the sides by an individual.

The ease of visualization of an emergency vehicle is a primary concernto emergency personnel regardless of the location of the observer. Inthe past, optimal observation of emergency lights has occurred when anindividual was either directly in front of, or behind, an emergencyvehicle. Observation from the sides, or at an acute angle relative tothe sides, frequently resulted in reduced observation of emergencylights during an emergency situation. A need therefore exists to improvethe observation of emergency lights for a vehicle regardless of thelocation of the observer. A need also exists to improve the flexibilityof placement of emergency lights upon a vehicle for observation byindividuals during emergency situations.

In the past, flashing light signals emanating from light bars have beenused to signal the presence of an emergency situation necessitatingcaution. A need exists to reduce the size of light sources on anemergency vehicle and to improve the efficiency of the light sourcesparticularly with respect to current draw and reduced aerodynamic drag.A need also exists to enhance the flexibility of positioning of lightsources about a vehicle for observation by individuals. In order tosatisfy these and other needs, more spatially efficient light sourcessuch as LED's are required. It is also necessary to provide alternativecolored LED light sources which may be electrically controlled for theprovision of any desired pattern of light signal such as flashing,alternating, pulsating, oscillating, modulating, rotational, and/orstrobe light effects without the necessity of spatially inefficient andbulky mechanical devices. In that regard, a need exists to provide aspatially and electrically efficient LED light source for use on anemergency vehicle which provides any of the above-identified types ofwarning light signals without the necessity of mechanical devices. Inaddition, a need exists to provide a spatially and electricallyefficient LED light source for use on an emergency vehicle whichprovides a flashing, alternating, pulsating, rotating, modulated,oscillating, and/or strobe light effect or combinations thereof withoutthe necessity of mechanical devices.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A warning signal light according to the principles of the invention isindicated generally herein as numeral 10. FIGS. 1 and 2 depict light bar70 mounted to an emergency vehicle 104. Light bar 70 includes base 72,mounting means 74, cover 82, and warning signal lights 10. Also includedin light bar 70 are gyrators 90 used to impart motion to warning signallights 10.

Referring to FIGS. 3 and 9, warning signal light 10 comprises lightsupport 12, light sources 30, controller 50 (shown in FIG. 11), andconnecting portion 40 for attaching the warning signal light 10 to lightbar 70 or gyrator 90. The warning signal light 10 operates to create awarning signal for use by an emergency vehicle 104 by selectivelyactivating light sources 30 using controller 50. Alternatively, warningsignal light 10 may be formed of a solitary LED light source 30 at thediscretion of an individual.

Light sources 30 are preferably light emitting diodes (LED's) and aregenerally arranged in aligned columns 32 and rows 34 as shown in FIG. 7and 9. Each of the light emitting diodes (LED's) may have shoulderportion 38 adjacent LED support 12 and dome 36. LED's 30 are situated tobe in electric communication with controller 50 and a power supply, abattery, or power source. The use of light emitting diodes (LED's) toreplace traditional halogen, incandescent, or gaseous discharge xenonlamps reduces heat generation, current draw, and electromagneticemissions, while increasing lamp life and producing a more true outputlight color.

The controller 50 is used to selectively activate columns 32, rows 34,or individual LED's 30, to illuminate any number of a plurality ofvisually distinct types of warning light signals at any moment; toilluminate more than one of a plurality of visually distinct types ofwarning light signals simultaneously at any moment; to illuminate one ofa plurality of combinations or patterns of visually distinct warninglight signals at any moment, or over any desired period of time, or toilluminate more than one of a plurality of combinations or patterns ofvisually distinct warning light signals over any desired period of time.The plurality of visually distinct warning light signals may include,but are not necessarily limited to, a strobe light signal, a pulsatinglight signal, an alternating light, a modulated light signal, a flashinglight signal, the illusion of a rotating or an oscillating light signal,a reverse character message, or images such as arrows. It should benoted that the controller 50 may also incorporate into any selectedwarning light signal variable or modulated power intensity to facilitatethe provision of a desired unique lighting effect. For example, thecontroller 50 may illuminate one or more LED light sources 30 toestablish a single warning light signal at a given moment.Alternatively, the controller 50 may illuminate one or more lightemitting diode light sources 30 to provide two or more warning lightsignals at any given moment. Further, the controller 50 maysimultaneously, consecutively, or alternatively, illuminate one or moreLED light sources 30 to establish any desired combination or pattern ofilluminated visually distinct warning light signals at any given momentor over a desired period of time. The combination and/or pattern ofvisually distinct warning light signals may be random or may be cycledas desired by an individual. The illumination of one or more patterns orcombinations of warning light signals facilitates the continuedobservation by an individual. Occasionally, the concentration orattention of an individual is diminished when exposed to a repetitive orto a monotonous light signal. The desired purpose for illumination of awarning light signal is thereby reduced. The provision of a pattern,combination, and/or random illumination of visually distinct warninglight signals maximizes the concentration or attention to be receivedfrom an individual observing a warning light signal. The purpose of thewarning light signal is thereby promoted.

FIGS. 11A, 11B, and 11C show an embodiment of controller 50 capable ofselectively activating columns 32, rows 34 or individual LED's 30.Controller 50 generally comprises microprocessor 52 and circuitry 53 andis preferably contained within, attached to, or an element of, LEDsupport 12. It is envisioned that controller 50 may be programmed by anexternal controller 55 and powered through cable R.

In one embodiment, controller 50 generally comprises circuit board 54 orLED mounting surface having microprocessor 52 attached to a low voltagepower supply, battery, or electrical source 56. Microprocessor 52 isconfigured through circuitry 53 to selectively activate columns 32 ofLED's 30. Transistors Q9 and Q10 are in electronic communication withmicroprocessor 52, power supply, battery, or electrical source 56, andtheir respective columns 32.9 and 32.10 of LED's 30. Columns 32 of LED's30 are connected to transistors Q1-Q8, which are in turn connected tomicroprocessor 52 through resistors R1-R8. Microprocessor 52 is capableof selectively activating transistors Q1-Q8 to allow current flowingthrough transistors Q9 and Q-10 to activate the selected column 32 ofLED's 30. This circuit is capable of producing a strobe light signal, analternating light signal, a modulated signal, a revolving light signal,a pulsating light signal, an oscillating light signal, or flashing lightsignal, a reverse character message, or images such as arrows.

In one embodiment, a rotating or oscillating light signal may beestablished by the sequential illumination of entire columns 32 of LED's30 by turning a desired number of columns on and then sequentiallyilluminating one additional column while turning another column 32 off.Alternatively, the rotating or oscillating warning light signal may becreated by selectively activating columns 32 of LED's 30.

A clockwise revolving light signal may be created by performing steps1-19 in descending order then repeating the steps. An oscillating lightsignal may be created by performing: (a) steps 7 through 16 in ascendingorder; (b) steps 7 through 16 in descending order; and (c) repeating (a)and (b).

A second embodiment of controller 50 provides a means for activatingLED's 30 individually to allow for greater flexibility in the type ofwarning light signal created. This embodiment of the invention iscapable of displaying information in different colors or patterns.Depending on the size of the display, it may be necessary to scroll thesymbols or characters across the display to accommodate for a largervisual appearance. It is envisioned that the mirror image of patterns,symbols, or characters could be displayed making the message easilyreadable by drivers viewing the signal in a rear view mirror. It is alsoenvisioned that this embodiment of the invention could display arrowsindicating a direction a vehicle is to travel or other images as shownin FIG. 2. In addition, combinations of warning signal lights, directionarrows, and other information carrying signals or images, could bedisplayed simultaneously by the invention.

LED support 12 is envisioned to have several embodiments. Oneembodiment, shown in FIG. 9, consists of a panel 14 having front 16,back 18, top 20, bottom 22 and sides 24. LED's 30 are arranged on front16, with domes 36 extending therefrom, in columns 32 and rows 34. LED's30 are in electric communication with controller 50 which may becontained or sealed within LED support 12 to provide protection from theelements.

Another embodiment of warning signal light 10 is depicted in FIG. 10 andFIG. 10.A. Here the backs 18 of two panels 14 are attached together toallow for a light signal to be produced on two sides. The two panels 14form LED support 12. Alternatively, it is envisioned that a single panel14 having LED's arranged about front 16 and back 18 could be used aswell.

FIGS. 6 and 8 show further embodiments of warning signal light 10. InFIG. 8, panels 14 are used to form an LED support 12 having four sidesand generally shaped as squared. FIG. 6 shows panels 14 connected toform an LED support 12 having three sides and generally triangular inshape. In both embodiments, LED's 30 are arranged about the fronts 16 ofthe panels 14. It is further envisioned that panels 14 may be integralto each other.

Yet another embodiment of warning signal light 10, consists of aflexible panel 14 and controller 50 to allow LED support 12 to be formedinto various shapes. FIG. 5 shows LED support 12 formed into a cylinder.Further variations include the use of flexible panels 14 to form othershapes such as semicircles (FIG. 12) or to simply conform to a surfaceof an emergency vehicle (FIGS. 13 and 14). This embodiment isparticularly useful for undercover vehicles which generally position thewarning signal lights inside the vehicle. For example, panel 14 could beattached to the front, rear, or side window of an undercover policevehicle.

It should be noted that numerous other shapes could be formed frompanels 14 including those formed from combinations of flat, curved, andflexible panels at the preference of an individual.

In each of the embodiments discussed above, the array of LED's 30 may beformed of the same or differently colored LED's. Generally, each column32 or row 34 may consist of a series of differently colored LED's.Controller 50 may be configured to select the color of the LED's to beilluminated forming the light signal. Accordingly, the user may select ablue, red, white, yellow, green, or amber color or any combinationthereof to be used as the color of light signal. Alternatively, thewarning signal 10 may be formed of individual LED's 30 which may beselectively illuminated at the discretion of an individual.

It is envisioned that the controller 50 may control warning signallights 10 having multiple sides (FIGS. 5, 6, 8, 10, and 10.A) such thateach side is capable of producing warning light signals or combinationwarning light signals that are independent and/or different from thoseproduced upon the other sides. For example, the squared shape warningsignal light shown in FIG. 8 may produce or simulate a red revolvinglight on first side 15.1, while second side 15.2 is simultaneouslyproducing a blue oscillating light, while third side 15.3 is producingor simulating a stationary white light, and while fourth side 15.4 isproducing a white strobe light.

Another embodiment of warning signal light 10 is depicted in FIGS. 1 and2 as light bar 70 which extends from driver side 100 to passenger side102 of emergency vehicle 104. Cover 82 protects light bar 70 from theelements. Each side of light bar 70 may have LED's 30 to produce orsimulate warning light signals on each side of emergency vehicle 104.Furthermore, controller 50 may be used to create multiple warning lightsignals on each side of light bar 70. For example, controller 50 maycreate a simulated revolving blue light positioned at front passengerside 102 of light bar 70, oscillating white lights positioned at frontdriver side 100, and yellow arrows there between. Additional oralternative warning light signals may be produced out the back 18 andsides of light bar 70. It is further envisioned that light bar 70 mayconsist of a single light source, a single row of light sources or alarge array of LED's 30 across each side FIG. 10.A. This embodimentprovides the largest display and, therefore, is best suited to displaydesired combinations of warning lights and images. It should be notedthat the identified types of warning light signals, combinations and/orpatterns of warning light signals, may also be reproduced through theillumination of a single row of LED light sources 30.

Mechanical rotation and oscillation of warning signal lights 10 aboutaxis A is possible by way of attachment to gyrator 90 depicted in FIG.3. Gyrator 90 mounted to light bar 70, generally comprises electricmotors 96 having cables 97. Gyrator 90 is configured to receiveconnecting portion 40 of warning signal light 10. Cable 97 is preferablyconnected to a power supply and either an external controller 55 orcontroller 50.

Gyrator 90 may be capable of rotating or oscillating warning signallight 10 about a single or dual axis of rotation A. FIG. 3 shows gyrator90 configured to rotate or oscillate warning signal light 10 about avertical axis A by way of motor 96.1 and oscillate warning signal light10 about a horizontal axis A by way of motor 96.2. Rotation oroscillation of warning signal light 10 about vertical axis A isaccomplished through direct attachment of connecting portion to motor96.1. Oscillation of warning signal light 10 about horizontal axis A isaccomplished by attaching swivel arm 99 to bracket 99.1 and post 99.2which is mounted to motor 96.2.

Alternative methods for imparting rotation or oscillation motion towarning signal light 10 may be accomplished through the use of electricmotors, toothed gears, and worm gears. In addition, maintainingelectrical communication between a power supply and an externalcontroller 55 with a revolving or oscillating warning signal light 10may be accomplished using brushes or other means without sacrificing theoperation of the warning signal light 10.

In another embodiment as depicted in FIGS. 13 and 14, emergency vehicle104 may include a front or rear windshield 106. The front or rearwindshield 106 is generally angularly offset with respect to the vehicleat an approximate angle of 45 degrees. In this embodiment, the mountingof a panel 14 of light sources 30 in flush contact with the interior ofa front or rear windshield 106 occurs through the use of angular offsets108 for the light sources 30 such that light emitted from the lightsources 30 occur at a horizontal visual line (V) which is substantiallyparallel to the plane of a vehicle and not at an approximate angle of 45degrees upward, which corresponds to the angle for the front or rearwindshield 106.

In this embodiment, the ease of visualization of the light source 30 issignificantly enhanced by the downward angular offsets 108 whichposition the light sources 30 along parallel visual lines of sight (V).LED supports 12 or panels 14 may then be positioned in any desiredlocation within the interior of a vehicle in flush contact or proximateto the front or rear windshield 106. A suitable cable 97 is required toprovide electrical power for illumination of the light sources 30. Itshould be noted that the angle of incidence for the angular offsets 108may vary considerably dependent upon the make or model for the vehicleto include the warning signal lights 10.

It should be further noted that the warning signal light 10 may be usedwith an automobile, motorcycle, snowmobile, personal water craft, boat,truck, fire vehicle, helicopter, and/or any other type of vehiclereceptive to the use of warning signal lights 10. It should be furthernoted that LED support 12 or panel 14 may be mounted to the interior topdashboard of a vehicle proximate to the front windshield 106 or to theinterior top rear dashboard proximate to the rear windshield 106 of avehicle.

Mounting of a light support 12 or panel 14 to either the front or reardashboards may minimize the necessity for inclusion of angular offset108 for the light sources 30. It should be further noted that LEDsupports 12 or panels 14 may be releasably affixed to the interior ofthe front or rear windshields 106 via the use of suction cups,hook-and-loop fabric material such as Velcro®, and/or any otherreleasable affixation mechanism at the preference of an individual. Anindividual may then adjust and reposition the location of the lightsupport 12 or panels 14 anywhere within the interior of a vehicle asdesired for maximization of visualization of the warning signal lights10.

In another alternative embodiment as depicted in FIG. 15, warning signallight 10 may function as a remote, revolving, or stationary beacon. Inthis embodiment, LED support 12 or panel 14 is preferably releasablyconnected to a transportable support 120 via the use of a bracket. Thetransportable support 120 may be a tripod having telescoping legs or maybe any other type of support as preferred by an individual. In thisembodiment, LED light support 12 or panel 14 is electrically connectedto an elongate electrical extension cable 97 which may include anydesired adapter for electrical connection to a power source which may bea vehicle. The remote light support 12 or panel 14 may also includeplug-in adapters for electrical connection to any desired electricalpower source other than a vehicle as is available.

The transportable support 120 may also include gyrator 90 as earlierdescribed to provide a desired rotational or oscillatory motion forwarning signal light 10. A controller 50 having a microprocessor 52 mayalso be integral to, or in electrical communication with, LED's 30 forthe provision of multi-colored lights, flashing, alternating, modulated,moving characters, arrows, stroboscopic, oscillating and/or revolvingwarning light signals as desired by an individual. In this embodiment,the warning signal light 10 may be physically separated from anemergency vehicle 104 any desired distance to facilitate or enhance thesafety of a potentially dangerous situation necessitating the use ofwarning signal lights 10. In addition, it should be noted that a seriesof remote warning signal lights 10 may be electrically coupled to eachother for any desired distance to again facilitate the safety of asituation necessitating the use of warning signal lights 10.

FIG. 16 shows a perspective view of a xenon lamp 1. Xenon lamp 1 has abase pedestal 2 which is typically formed of rubber, plastic, or otherinsulating material. Base pedestal 2 has a top surface 3 which maysupport a glass tube 4 which may have a looped curve such that an anodeend and a cathode end are each supported on a top surface. The anode andcathode ends may be sealed and respective electrical conductors 5 and 6may pass through the sealed ends and through the top surface 3. Atrigger wire 7 may be helically wound about the exterior surface of theglass tube 4 and the ends of the trigger wire 7 may be passed throughthe top surface 3 of the base pedestal 2 to form a third conductor onthe underside of the base pedestal 2.

Base pedestal 2 may have an upper cylinder portion 8 extending from alower shoulder all of which may extend above the top surface 3. Theupper cylindrical portion 8 may include an upper shoulder 9. A glassdome (not shown) may be sized to fit over the xenon lamp 1 and glasstube 4 for resting on the upper shoulder 9. The glass dome may bepreferably made from a transparent or silicate glass material capable ofwithstanding heat stress. The outer diameter of the glass dome istypically about one inch which is sized to fit through the conventionalopening in a typical vehicle lamp fixture. The exterior glass domesurface typically has a much lower temperature during operation than theexterior surface of the glass tube 4 forming a part of the xenon lamp 1.The temperature drop between the glass tube 4 and the glass domefacilitates the use of coloring of the dome to provide a colored lamp byvirtue of the xenon light intensity passing through the colored dome.

The xenon lamp 1 is preferably aligned for insertion into a conventionalopening 248 of a light reflector 260 (FIGS. 20 and 21). The lightreceptacle opening 248 in the light reflector 260 is typically about oneinch in diameter; and the glass dome and base pedestal 2 are preferablysized to fit within the light receptacle opening 248. The xenon lamp 1in its final construction may include a cover plate (not shown) affixedover the bottom opening of the base pedestal 2 for affixation to a lightreflector 260 via the use of screws which pass through the screwapertures 9.1. The anode, cathode, and trigger wire 7 preferablytraverse the base pedestal 2 and may include a plug 9.2 which is 30adapted for engagement to a controller/power supply for a motor vehicle.

The light reflector 260 may be a conventional light reflector of thetype found in vehicles having a clear plastic or glass lens cover. Theglass or lens cover may be fitted over the front edge of the reflector260 in a manner which is conventional with vehicle lamps. It should benoted that the light reflector 260 may be parabolically or other shapedat the preference of an individual. The light reflector 260 may bemounted to a motor for rotation about a vertical axis. In thisembodiment the light source/replacement lamp 200 may be integrallyconnected or affixed to the reflector 260 for simultaneous rotationabout the vertical axis during use of the motor. Alternatively, thelight source/replacement lamp 200 may be fixed proximate to the verticalaxis where the light reflector 260 is rotated around the stationaryreplacement lamp 200 to provide for the visual appearance of arotational light source.

The glass domes as used with the xenon lamps 1 may be colored with anycolor as preferred by an individual including but not limited to red,blue, amber, green, and/or white. It should be noted that the lightfixture incorporating the light reflector 260 may be a headlight fixtureor a turn signal light fixture where the xenon lamp 1 is mounted intothe light reflector 260 on either side of a centrally-mounted halogenlight bulb which may be used as a headlight lamp. In this case, thelight fixture could perform its normal function as a headlight and couldalternatively flash several additional colors, depending upon the needsof the user. This configuration provides an emergency flashing lightconstruction which is wholly concealed within a normal head lamp of avehicle and is, therefore, not readily visible from outside the vehicleunless the lights are flashing. This construction may find applicationin an unmarked emergency vehicles such as might be used by some lawenforcement officers.

In operation, the LED replacement lamp 200 may be constructed as areplacement part for a conventional incandescent or xenon gaseousdischarge lamp. The standard mounting base 204 and LED support assembly212 may be sized to readily fit into the same light opening as anincandescent lamp would require, although it is apparent the electricaldriving circuit for the LED replacement lamp 200 may requiremodifications to accommodate the LED operating principles.

LED warning signal lamp 200 may be used in a variety of locations abouta vehicle. It should be noted that the use of the LED warning signallamps 200 are not necessarily limited to positioning adjacent to thehead lamp or headlight, tail light, or turn signal illumination devicesfor an emergency vehicle 104. The LED warning signal lamp 200 may beused as a rotational, pulsating, or oscillating reflector light withinthe interior adjacent to a front, rear, and/or side window of a vehicle.

It is also envisioned that the controller 50 may control warning signallights 200 independently of one another such that each warning signallamp 200 is capable of producing warning light signals which areindependent and/or different from those produced at another locationabout an emergency vehicle 104. For example, a front left location mayproduce a red colored light while simultaneously a front right locationmay produce an amber colored light and a right rear location may producea green colored light and a left rear location may produce a bluecolored light. The controller 50 may then alternate the color of thelight illuminated from the warning signal lamp 200 in each area asdesired by an individual. Alternatively, the controller 50 maysequentially activate warning signal lamps 200 positioned about anemergency vehicle 104 to simultaneously produce a desired color oralternating sequence of colors. It should also be noted that thecontroller 50 may simultaneously illuminate all LED warning signal lamps200 to produce a flashing or strobe light which may be particularlyuseful in certain emergency situations. It should be further noted thatthe controller 50 may selectively illuminate individual LED warningsignal lamps 200 in any desired color, pattern, and/or combination asdesired by an individual.

Referring to FIG. 17 in detail, an LED replacement lamp 200 is depicted.In this embodiment the LED replacement lamp 200 includes a standardmounting base 204 which preferably includes a top surface 206. Extendingupwardly from the top surface 206 is preferably an upper cylindricalportion 208 which includes an upper shoulder 210. Extending upwardlyfrom the upper shoulder 210 is preferably an LED support assembly 212which includes one or more LED lamp modules 213. The LED lamp modules213 may be of the same or different colors at the discretion of anindividual. A wire 202 is preferably in electrical communication withthe plurality of LED lamp modules 213 to provide for electricalcommunication with the controller 50 to individually activate orilluminate LED lamp modules 213 as preferred by an individual. A plug-inconnector 40 is preferably coupled to the wire 202 for engagement to thecontroller 50 and/or power source of an emergency vehicle 104.

The LED replacement lamp 200 is preferably adapted to be positioned in aone inch light receptacle opening 248 (approximate size) which has beenpreviously placed through the backside of a reflector assembly 260. TheLED replacement lamp 200 is preferably used to replace a xenon gaseousdischarge lamp or incandescent lamp as previously mounted to a basewhich is inserted into opening 248 in a reflector assembly 260.Illumination of one or more individual LED lamp modules 213, as mountedin the reflector assembly 260, enables the reflector assembly/lens totake on the appearance of a warning signal or emergency signaling lamp.The LED replacement lamp 200 preferably replaces the xenon gaseousdischarge or incandescent lamp assemblies with high brightness, longlife LED technology.

Referring to FIG. 18, an incandescent lamp or quartz halogen H-2 lamp isdepicted and in general is indicated by the numeral 220. Theincandescent lamp assembly 220 is preferably formed of a standardmounting base 222. A vertical post 224 preferably extends upwardly fromthe standard mounting base 222. The incandescent light bulb 226 ispreferably mounted in the vertical post 224. The vertical post 224 mayextend below the standard mounting base 222 to provide for electricalcoupling with a wire 228 which preferably includes a standard pinconnector 230. The standard pin connector 230 is preferably adapted forelectrical communication to a power supply and/or controller 50 foractivation of the incandescent lamp assembly 220. The incandescent lampassembly 220 may be stationary or mounted in a rotational lightreflector 260 as desired by an individual. The light bulb 226 may be ahalogen H-2, 55 watt, lamp at the discretion of an individual.

As depicted in FIG. 19, LED replacement lamp 200 is adapted to replacethe incandescent lamp assembly 220 in a stationary or rotational lightreflector 260. The LED replacement lamp 200 as depicted in FIG. 19preferably includes a standard mounting base 234 and a vertical post236. It should be noted that the vertical post 236 may extend upwardlyfrom the standard mounting base 234 and may alternatively extend belowthe standard mounting base 234 at the preference of an individual. AnLED mounting area 238 may be preferably integral or affixed to the uppersection of the vertical post 236.

The wire connector 244 is preferably adapted to beplugged into a controller 50 or power supply. Communication is therebyprovided for selective illumination of the individual LED module lamps240. It should be noted that a group of individual LED module lamps 240are mounted in the LED mounting area 238. It should also be noted thatthe LED replacement lamp 200 is preferably adapted to replace theincandescent lamp assembly 220 or a xenon gaseous discharge lampassembly base of FIGS. 16 or 18. The purpose of the LED replacement lampassembly 200 is to replace existing xenon gaseous discharge andincandescent lamps with new LED technology while simultaneouslyutilizing existing standard bases in a standard lamp enclosure. Forexample, an individual may choose to replace a halogen “H-2” 55 wattlamp with an “LED-2” lamp in an existing rotating light fixture with noother structural modifications, yet achieving the advantages of lesspower consumption, greater reliability, easier installation, less RFemissions (which reduces interference with radio or electronicequipment), cooler operating temperatures, simplified circuitry, longerlife, greater durability and duty capability, and simultaneouslyproviding pure and easier-to-see color light output.

As depicted in FIG. 20, a rotational light reflector 246 is disclosed.The rotational light fixture 246 includes a reflector assembly 260having a standard opening 248. The incandescent light assembly 220 ispreferably positioned in the standard opening 248 for extension of thevertical post 224 outwardly from the reflector assembly 260 forpositioning of the light bulb 226 in a desired location. Light emittedfrom the standard halogen light bulb 226 preferably reflects off theparabolic-shaped reflector assembly 260 for transmission of light in adirection as indicated by arrows AA for visualization by individuals.Reflector assembly 260 and light source 226 may be rotated via the useof gears 250 which are preferably driven by electrical motors not shown.In this manner, the rotational light fixture 246 including the reflectorassembly 260 may be rotated at any desired velocity as preferred by anindividual.

Rotational light fixture 252 preferably includes a reflectorassembly 260 which may be parabolic in shape for the transmission oflight along a common axis as depicted by arrows BB for visualization byan individual. In this embodiment, the individual LED module lamps 240may be positioned to the front of the reflector assembly 260 through theuse of a frame 254. The frame 254 may be integral or connected to a gear250 as desired by an individual. The gear 250 may be driven by a motorfor rotation of the light fixture 252. It should be noted that theindividual LED module lamps 240 are preferably in electricalcommunication with a power source not shown.

It should be further noted that the rotational light fixture 252 mayalso be adapted for the provision of an oscillating or pulsating warninglight signal at the preference of an individual.

An alternative replacement LED lamp 200 is depicted in FIGS. 23-25. Inthis embodiment the LED replacement lamp 200 includes a standardmounting base 270. The standard mounting base 270 also preferablyincludes a plurality of teeth 272. The teeth 272 are preferably adaptedfor mating coupling with gears integral to a motor and/or reflector 260,or rotational light fixture 246 to facilitate rotation and/oroscillation of the replacement LED lamp 200. The standard mounting base270 also preferably includes a top surface 274 opposite to the teeth272.

An upper cylinder portion 276 is preferably adjacent to the top surface274. The upper cylinder portion 276 preferably includes an uppershoulder 278. Extending upwardly from the upper shoulder 278 ispreferably a circuit board, LED mounting surface, or support 280 whichpreferably includes one or more LED illumination sources 282. The LEDillumination sources 282 may be of the same or different colors at thepreference of an individual. A wire 284 is preferably in electricalcommunication with the LED illumination sources 282 to provide forcommunication and contact with the controller 50 for combination and/orindividual illumination of the LED illumination sources 282. A standardplug-in connector may be integral to the wire 284 to facilitate couplingengagement to the controller 50 and/or power source for a vehicle 104.

The circuit board or LED mounting surface 280 is preferably adapted tohave a first side 286 and an opposite side 288. Preferably a pluralityof LED illumination sources 282 are disposed on both the first side 286and the opposite side 288 of the replacement lamp 200.

A glass dome or protector 290 is preferably adapted for positioning overthe circuit board or LED mounting surface 280 for sealing engagement tothe top surface 274 of the standard mounting base 270. The glass dome290 may be formed of transparent plastic material or a transparent orsilicate glass material capable of withstanding heat stress at thepreference of an individual. It should be further noted that the glassdome 290 preferably protects the circuit board or LED mounting surface280 and the LED illumination sources 282 from contamination and fromexposure to moisture during use of the replacement lamp 200. In thisregard, the sealing lip 292 of the glass dome 290 preferably is securelyaffixed to the top surface 274 to effectuate sealing engagementtherebetween. The outer diameter of the glass dome 290 is preferablyabout one inch which is sized to fit within the conventional opening 248in a typical lamp fixture or reflector assembly 260.

The replacement lamp 200 depicted in FIGS. 23, 24, and 25 is alsoadapted to be positioned in a one inch light receptacle opening 248which has been placed into a reflector assembly 260. Illumination of oneor more individual LED illumination sources 282 as disposed on thecircuit board or LED mounting surface 280 enables the replacement lamp200 to take on the appearance of a warning signal or emergency signalinglamp.

The replacement lamp as depicted in FIGS. 23, 24, and 25 mayalternatively permit the circuit board 280 to extend below the uppershoulder 278 to facilitate affixation and positioning relative to thestandard mounting base 270.

The controller 50 may regulate the illumination of the LED light sources282 individually, or in combination, to provide a desired warninglighting effect for the replacement lamp 200. Also, the controller 50may illuminate the LED light sources 282 individually, or incombination, independently with respect to the first side 286 and theopposite side 288 to provide different warning light effects to beobserved by an individual dependant upon the location of the personrelative to the replacement lamp 200. The controller 50 may alsosimultaneously or independently regulate the power intensity to the LEDillumination sources 282 to provide for a modulated or variable lightintensity for observation by an individual. It should also be noted thatthe LED illumination sources 282 may be formed of the same or differentcolors at the preference of an individual to provide a desired type ofwarning light effect for the replacement lamp 200.

In an alternative embodiment, the LED warning signal lamps 10 or LEDreplacement lamps 200 may be electrically coupled to a controller 50which in turn is used to provide a modulated power intensity for thelight source. A modulated power intensity enables the provision ofvarious power output or patterns of illumination for creation of aplurality of visually distinct warning light signals without the use ofmechanical devices. In these embodiments, the controller 50 illuminatesselected light sources 282 and the controller 50 may also regulateand/or modulate the power supplied to the light source 282 therebyvarying the intensity of the observed light. In addition, the controller50 may modulate the power supplied to the LED warning signal lamps 10 orLED replacement lamps 200 in accordance with a sine wave pattern havinga range of 0 to full intensity. At the instant of full intensity, thecontroller 50 may also signal or regulate a power burst for observationby an individual. The controller 50 operating to regulate and/ormodulate the power intensity for the warning signal lamps 10 or LEDreplacement lamps 200 in conjunction with illumination andnon-illumination of selected light source 282 may establish theappearance of a rotational warning light source or pulsating lightsource without the necessity of mechanical rotational or oscillatingdevices. The current draw requirements upon the electrical system of anemergency vehicle 104 is thereby significantly reduced. Spatialconsiderations for an emergency vehicle are also preferably optimized byelimination of mechanical, rotational and/or oscillation devices.

The controller 50 may also regulate the modulated power intensity forthe provision of a unique variable intensity warning light signal. Theunique variable intensity light source is not required to cycle througha zero intensity phase. It is anticipated that in this embodiment thatthe range of intensity will cycle from any desired level between zeropower to full power. A range of power intensity may be provided betweenthirty percent to full power and back to thirty percent as regulated bythe controller 50. It should also be further noted that an irregularpattern of variable power intensity may be utilized to create a desiredtype of warning light effect. In addition, the controller 50 may alsosequentially illuminate adjacent columns 32 to provide a unique variablerotational, alternating, oscillating, pulsating, flashing, and/orcombination variable rotational, alternating, pulsating, oscillating, orflashing visual warning light effects. A pulsating warning light signalmay therefore be provided through the use of modulated power intensityto create a varying visual illumination or intensity effect without theuse of rotational or oscillating devices. The controller 50 may alsomodulate the power intensity for any combination of light sources 30 or282 to provide a distinctive or unique type of warning light signal.

The use of a controller 50 to provide a modulated power intensity for alight source may be implemented in conjunction with replacement lamps200, flexible circuit boards having LED light sources 30, paneledcircuit boards or LED mounting surfaces having LED light sources 30,light bars 70 having LED light sources 30, a cylindrical, square,rectangular, or triangular-shaped circuit boards having LED lightsources 30 and/or any other type or shape of LED light sources includingbut not limited to the types depicted in FIGS. 1-50 herein.

Further, the controller 50 may be utilized to simultaneously providemodulated or variable light intensity to different and/or independentsections, areas, and/or sectors 326 of a light source (FIG. 35). Also,the controller 50 may be utilized to simultaneously provide modulated orvariable light intensity to different and/or independent sectors, areas,and/or sections 326 of the forward facing side or rearward facing sideof the light bar 70 for the provision of different warning light signalsor a different warning light effects on each side. In this embodiment itis not required that the forward facing and rearward facing sides of thelight bar 70 emit the identical visual patterns of illuminated lightsources 30. The controller 50 may regulate and modulate the variablelight intensity of any desired sector 326 of the forward facing sideindependently from the rearward facing side of the light bar 70. Thecontroller 50 may thereby provide any desired pattern and/or combinationof patterns of warning light signals through the utilization of variableand/or modulated light intensity for the forward facing side, and adifferent type or set of patterns and/or combination of patterns ofwarning light signals having variable or modulated light intensity forthe rearward facing side of the light bar 70 as desired by anindividual. It should be further noted that an infinite variety ofpatterns and/or combinations of patterns of warning light signals may beprovided for the forward facing side and the rearward facing side of thelight bar 70 a the preference of an individual.

The use of the controller 50 to modulate the power intensity for a lightsource 30 to provide a unique warning light signal may be utilizedwithin any embodiment of an LED light source 10, light bar 70 lightsupport, replacement lamp 200 or reflector assembly as described inFIGS. 1-50 herein.

It should be further noted that the modulation of the power intensityfor a light source 30 or replacement lamp 200 may be used inconjunction, or as a replacement to, the sequential illumination ofrows, columns, and/or individual LED light sources 30 to provide adesired type of unique warning light effect.

The modulated power intensity may be regulated by the controller 50 tocreate a unique warning light signal within a single sector 326 or inconjunction with multiple separated or adjacent sectors 326 of light bar70 or light support for the provision of any desired composite emergencywarning light signal. All individual LED light sources 30 within a lightbar 70 or light support may be simultaneously exposed to incrementallyincreased modulated power intensity to provide for an incrementalincrease in illumination. A power burst at full power may be provided atthe discretion of an individual. The modulation of the power intensityin conjunction with the incremental increase in illumination of all LEDlight sources 30 within light bar 70 or light support may provide theappearance of rotation of a warning light signal when observed by anindividual. The power exposed to the individual light sources 30 maythen be incrementally decreased at the preference of an individual. Itshould be noted that the power is not required to be regularlyincrementally increased or decreased or terminated. It is anticipatedthat any pulsating and/or modulated variable light intensity may beprovided by the controller 50 to the LED light sources 30.

It should also be noted that all individual LED light sources 30 withina light bar 70 are not required to be simultaneously and incrementallyilluminated to provide for the appearance of rotation. For example, alight bar 70 or light support may be separated into one or more distinctsegments 326 which are formed of one or more columns 32 of LED lightsources 30, a particular segment 326 may be selected as a centralillumination band which may receive the greatest exposure to themodulated or variable power intensity and, therefore, provide thebrightest observable light signal. An adjacent segment 332 may bedisposed on each side of the central illumination band 330 which in turnmay receive modulated or variable power intensity of reduced magnitudeas compared to the central illumination band 330. A pair of removedsegments 333 may be adjacent and exterior to the segments 332, and inturn, may receive exposure to a modulated power source of reducedintensity as compared to segments 332. The number of desired segmentsmay naturally vary at the discretion of an individual. The controller 50may thereby regulate a power source to provide a modulated or variablepower intensity to each individual segment 330, 332, or 333 (FIG. 35) toprovide for a unique warning light effect for the light bar 70 or lightsupport.

It should be further noted that light supports 12 may be flat and rigid,pliable, moldable, triangular, cylindrical, partially cylindrical,and/or any other shape as desired by an individual provided that theessential functions, features, and attributes described herein are notsacrificed.

The provision of a modulated power intensity to the light bar 70 orlight support may also be coupled with or in combination to thesequential illumination of columns 32 as earlier described. In thissituation, the warning light signal may initially be dim or off as theindividual columns 32 are sequentially illuminated and extinguished forillumination of an adjacent column or columns 32. The power intensityfor the illuminated column or columns 32 may simultaneously beincrementally increased for a combination unique rotational andpulsating modulated or variable warning light signal. In addition, thecontroller 50 may be programmed to provide the appearance of rotationpulsation and/or oscillation at the discretion of an individual.

Each individual LED light source 30 preferably provides an energy lightoutput of between 20 and 200 or more lumens as desired by an individual.

Each light support 12 may contain a plurality of rows 34 and columns 32of individual LED light sources 30. The light supports 12 are preferablyin electrical communication with the controller 50 and power supply. Thesupports 12 preferably are controlled individually to create a desiredwarning light signal for an emergency vehicle 104 such as rotation,alternating, oscillation, strobe, flashing, or pulsating as preferred byan individual. Each support 12 may be controlled as part of an overallwarning light signal or pattern where individual supports 12 may beilluminated to provide a desired type or combination light signal inaddition to the provision of a modulated or variable power intensity forthe light source 30.

Modulated power intensity may be regulated by the controller 50 tocreate the appearance of rotation within a single support 12 or inconjunction with multiple separated, independent or adjacent supports 12for the provision of a composite emergency warning light signal.

It should be noted that each portion, section, sector, or area 326 oflight bar 70 or light support may be controlled as part of an overallwarning light signal or pattern where individual sections or sectors 326may be illuminated to provide a desired type of warning light signalincluding but not limited to rotation and/or oscillation through the useof a modulated or variable power intensity. Alternatively, thecontroller 50 may provide for the random generation of light signalswithout the use of a preset pattern at the preference of an individual.

Controller 50 may be used to selectively activate individual LED's 30 tocreate a pulsating light signal, a strobe light signal, a flashing lightsignal, an alternating light signal, and/or an alternating coloredflashing light signal for an emergency vehicle.

Controller 50 provides a means for activating LED's 30 individually toallow for greater flexibility in the type of warning light signalcreated. This embodiment of the invention is also capable of displayinginformation in a variety of different colors or sequential illuminationof colors.

Referring to FIG. 33, the emergency vehicle 300 preferably includes alight bar or light support 302 which may include one or more panels ofLED light sources 306. A strip LED light source 308 may also be securedto the exterior of the emergency vehicle 300 at any location as desiredby an individual. It is anticipated that the strip LED light source 308may preferably encircle an entire emergency vehicle 300 to enhance thevisualization of the emergency vehicle 300 as proximate to an emergencysituation.

Referring to FIG. 34, the strip LED light source 308 is preferablycomprised of a circuit board 310 having an array 312 of individual LEDlight sources 306. The LED light sources 306 are preferably inelectrical communication with each other via electrical contacts 314.Each circuit board 310 is preferably in electrical communication with apower supply and/or controller 50 via the use of wires 316. Eachindividual LED light source 306 as included within a strip LED lightsource 308 may be enclosed within a reflector 370 to facilitate andmaximize light output along a desired visual line of sight. It should benoted that the LED light sources 306 preferably have maximumillumination at an angle of incidence approximately 40°-45° downwardlyfrom vertical. The strip LED light sources 308 preferably include aback-side. The back-side preferably includes an adhesive, magnetic, orother affixation device which may be used to secure the strip LED lightsources 308 to the exterior of an emergency vehicle 300 in any desiredpattern or location. The strip LED light sources 308 may also beenclosed within a transparent cover 324 which prevents moisture or othercontamination from adversely affecting the performance of the LED lightsources 306 during use of the strip LED light source 308.

Wires of adjacent strip LED light sources 308 may preferably beintertwined to extend across a vehicle for coupling to a power supply ata central location. The wires are preferably connected to the controller50 which may be used to regulate the illumination of individual LEDlight sources 306 and/or individual panels of the strip LED lightsources 308 to provide for the appearance of sequential, pulsating,alternating, oscillating, strobe, flashing, modulated, and/or rotationallights for an emergency vehicle 300. It should be noted that theindividual LED light sources 306 within the strip LED light source 308may be of a single or variety of colors as desired by an individual.Alternatively, adjacent strip LED light sources 308 may be electricallycoupled to each other in a parallel or series electrical connection forcommunication to a centrally located controller and power source.

The individual LED light sources 306 as incorporated into the array 312of the strip LED light sources 308 are preferably sturdy and do not failor separate from a vehicle 300 when exposed to rough operatingconditions. It should be further noted that any individual strip of LEDlight sources 308 may be easily replaced as required. The transparentcover 324 for the strip LED light sources 308 is preferably formed ofsturdy and resilient plastic material which prevents water penetrationand/or contamination to the circuit board 310 and/or individual lightsources 306. Each individual LED light source 306 preferably provides anenergy light output of between 20 and 200 or more lumens as desired byan individual.

The strip LED light sources 308 may individually be any size aspreferred by an individual. It is anticipated that the strip LED lightsources 308 may have the approximate dimensions of three inches inlength, three inches in width, and one-half inch in thickness for use inaffixation to the exterior of an emergency vehicle 300.

It should be noted, however, that any desired size of strip LED lightsources 308 may be selected by an individual for use in association withthe exterior of the emergency vehicle 300 including the use of a seriesof solitary light sources 306.

Referring to FIG. 35, a panel 304 of individual LED light sources 306 isdepicted. The panel 304 may form the illumination element for the stripof LED light sources 308 and/or light bar 70 or light support 12, 302 asaffixed to an emergency vehicle 300. Each panel 304 preferably containsa plurality of rows 34 and columns 32, 328 of individual LED lightsources 306. The panels 304 are preferably in electrical communicationwith the controller 50 and power supply (now shown). The panels 304preferably are controlled individually to create a desired warning lightsignal for an emergency vehicle 300 such as rotation, alternating,pulsating, sequencing, oscillation, modulated strobe, or flashing aspreferred by an individual. Each panel 304 may be controlled as part ofan overall warning light signal or pattern where individual panels 304may be illuminated to provide the appearance of rotation and/oroscillation motion through the use of a modulated power intensity lightsource without the use of mechanical devices.

It should also be noted that the strip LED light sources 308 may beorganized into distinct sections, segments, and/or sectors 326 forindividual illumination by the controller 50. Each distinct segment,section, and/or sector 326 may therefore be illuminated with a visuallydifferent and distinct type of light signal with, or without, modulatedor variable power intensity for the creation of a desired type of uniquewarning lighting effect for a vehicle. An infinite variety of colorand/or pattern combinations or sequences may be established for theemergency vehicle 300 through the use of the controller 50.

Modulated power intensity may be regulated by the controller 50 tocreate the appearance of rotation or pulsation within a single panel304, strip 308, or in conjunction with multiple separated or adjacentpanels 304 or strips 308 for the provision of a composite warning lightsignal as desired by an individual. The warning light signal for each ora group of panels 304 or strips 308 may also be regulated by thecontroller 50 for the provision of a modulated power intensity for anobservable warning light signal. All individual LED light sources 306within a panel 304 or strip 308 may also be exposed to incrementallyincreased modulated power intensity to provide for an incrementalincrease in illumination for a warning light signal. The modulation ofthe power intensity of LED light sources 306 within panel 304 or strips308 thereby may provide the appearance of rotation of a light signalwhen observed by an individual. The power modulation or light intensitycurve is anticipated to resemble a sine wave pattern when the warninglight signal provides the appearance of rotation (FIG. 43). The power tothe individual light sources 306 may then be incrementally decreased atthe preference of an individual. It should be noted that the power isnot required to be terminated. It should also be noted that eachindividual LED light source 306 is not required to receive the samelevel of power output from the controller 50. Therefore differentindividual LED light sources 306 may receive different power outputlevels within a single warning light signal. Individual LED lightsources 306 within panel 304 are not required to be simultaneously andincrementally illuminated to provide for the appearance of rotation. Itis anticipated that a pulsating and/or modulated variable lightintensity may be provided by the controller 50 for regulation of thepower output from thirty percent to maximum and back to thirty percentwhich affords a desirable type of pulsating modulated variable lighteffect.

The provision of a modulated power intensity to the panels 304 may alsobe coupled with or in combination to the sequential illumination ofcolumns 328 as earlier described. In this situation, the warning lightsignal may initially be dim or off as the individual columns 328 aresequentially illuminated and extinguished for illumination of anadjacent column or columns 328. The power intensity for the illuminatedcolumn or columns 328 may simultaneously be incrementally increased fora combination unique rotational and pulsating modulated light signal. Inaddition, the controller 50 may be programmed to provide the appearanceof rotation pulsation and/or oscillation at the discretion of anindividual.

It should be noted that the provision of a modulated light or powerintensity may be implemented in association with a light bar or lightsupport 302, a cylindrical panel, a strip of lights 308, flat panels304, or any other type of light source as desired by an individual foruse with an emergency vehicle 300.

Referring to FIGS. 48 and 49, an individual LED light source 306 isdepicted in detail. The LED light source 306 preferably include aceramic and/or heat resistant base 334. Centrally within the ceramic andheat-resistant base 334 is positioned a light source 336. The lightsource 336 is preferably enclosed within a protective cover 338.Extending outwardly from the individual light source 306 are a pair ofcontact paddles 340 which preferably provide for the electrical contactsfor illumination of the light sources 336 during use of the individuallight sources 306. The back of the LED light source 306 includes a slug342. The slug 342 is designed to be positioned within circular openings344 of a circuit board or LED mounting surface 346 (FIG. 36). Thecircuit board or LED mounting surface 346 preferably establishes a heatsink within an aluminum base or frame 348 as depicted in FIGS. 38 and39. The LED light sources 306 as depicted in FIGS. 48 and 49 preferablyprovide for a light intensity varying between 20 and 200 lumens orhigher at the discretion of an individual. The positioning of the slug342 in the circular openings 344 of the circuit board or LED mountingsurface 346 also preferably establishes a heat sink. A heat sink isdesirable because the individual LED light sources 306 may have asufficient level of power output during use to develop heat. As aresult, the slugs 342 are positioned within the circular opening 344 andmay be fully engaged to an adhesive for affixation to an aluminum base349 (FIGS. 38 and 39). This combination assists in the dissipation ofheat during use of the individual LED light sources 306 enhancing theperformance of the light support 302.

As may be seen in FIGS. 31, 32, 37 and 50, in an alternative embodiment,the light bar or light support 302 or panel 304 may be formed of asingle row of LED light sources 306. Within this embodiment, the LEDlight sources 306 are positioned within circular openings 344 of circuitboard or LED mounting surface 346 (FIG. 37). Circuit board 346 may beaffixed to aluminum base 348 through the use of adhesive including glassbeads where the circular openings 344 preferably establish a heat sinkfor the individual LED light sources 306. The use of adhesive includingglass beads to affix the LED light sources 306 and circuit board 346 tothe aluminum base 348 preferably assists in the creation of electricalcontact for the light bar or light support 302.

As depicted in FIG. 37 the top surface of the circuit board or LEDmounting surface 346 may include two reflectors or mirrors 350. Thereflectors or mirrors 350 are preferably elongate and are positionedsubstantially parallel to each other and are adjacent or aligned to therows of individual LED's 306. The reflectors or mirrors 350 preferablydiverge upwardly and outwardly from a position proximate to the LEDlight source 306 and aluminum base 348. As such, the mirrors 350 have aseparation distance which is narrow proximate to the LED light sources306, where the separation distance becomes larger as the distancevertically from the aluminum base 348 increases.

As earlier described, the brightest or most intense light of theindividual LED light sources 306 is provided at an acute angle ofapproximately 40° to 42°. The reflector or mirror 350 as angled upwardlyand outwardly relative to the row of LED light sources 306 reflectslight exiting the LED light sources 306 along a desired line of sightwhich corresponds to perpendicular observation by an individual. Thereflectors or mirrors 350 maximize the efficiency of the light sources306 by reflecting light along the line of sight to be observed by anindividual during an emergency situation. The reflectors or mirrors 350may have a polished or non-polished surface at the preference of anindividual depending on the brightness desired for the light support302. The reflectors or mirrors 350 may also include one or morereflective sections 374 and/or transparent or clear sections 372. Thetransparent or clear sections 372 and the reflective sections 374 aredescribed in detail with reference to FIGS. 27-30 herein. It should benoted that the surface of the reflectors or mirrors 350 may include anydesired combination of sections, patterns, stripes, rows, and/or columnsof clear or transparent sections 372 and/or reflective sections 374 asdesired by an individual for a reflection of light illuminated from theindividual LED light sources 306 during the provision of a warning lightsignal.

Wires 354 preferably connect the circuit board 346 to the power supplyand controller 50. A modulated power source as earlier described maythereby be provided to the light support 302 which includes thereflector or mirrors 350. In this embodiment, the sequentialillumination of individual LED's 306 may occur to provide a desired typeof warning light signal. Also, the circuit board 346 as engaged to thebase 348 may be separated into segments 326 of LED light sources 306 foruse in combination with a modulated power intensity electrical source.

As depicted in FIGS. 38 and 39, the frame 348 includes a base 349. Thebase 349 may include a holding cavity 358. In the holding cavity 358 ispreferably positioned a circuit board or LED mounting surface 360 whichincludes a plurality of circular openings 344. In each circular opening344, is preferably positioned an individual LED light source 306. Abovethe holding cavity 358 is preferably a first support 362 and a secondsupport 363. The first support 362 and second support 363 preferablyhave an angled interior edge 364. Each angled interior edge 364 ispreferably adapted to receive a reflector or mirror 350. Each mirror 350is preferably utilized to reflect light illuminated from an individuallight source 306 along a visual line of sight as depicted by arrow AA ofFIG. 39. The first and second supports 362, 363 also preferably includea positioning ledge or notch 366 which is adapted to receive a glass ortransparent plastic cover lens 368 which serves as a protector for theframe 348 and individual LED light sources 306.

Referring to FIG. 50, the frame 348 may be elongate having a first end380 and a second end (not shown). The first end 380 and the second endpreferably each include and affixation area 382 which may be threadedfor receiving engagement to a fastener 384 as preferred by anindividual. A bracket 386 may be rotatably engaged to the first end 380and second end at the preference of an individual by tightening of thefasteners 384 relative to the affixation areas 382.

The provision of a convex orconcave face 444, is utilized to assist in the creation of a uniquevariable light effect as observed by an individual. Light as emittedfrom the light source 402 may then be reflected at any desired angleother than perpendicular for observation by an individual. The pulsatingintensity of the light as observed by an individual may then be unique,especially when used in conjunction with the rotated reflector 434 andvariable or modulated power intensity from the controller 50. Inaddition, the use of a convex or concave reflector 444 may expand orenhance the observation of the warning signal light 400 by individualsbeyond a perpendicular line of sight.
